Depression

Sarah
I have pcos and depression. I'm gaining weight no matter how much I exercise and eat healthy. One day I weighed 175 and the next it was 180. This was after I excerisied for 2 hours and have been watching what I am eating for the past 2 weeks. I'm just not seeing the results I want and I'm feeling unlovable. 
I'm a Christian and am always asking myself why God would do this to me?
